Hi Lyor,
Yesterday I said you that no deadlock occurred with the new code changes, but I
spoke too early.... :(
I found a third thread deadlock on SSH client running our long run test always
during client/server disconnection.
The deadlock is as follows :
Thread #22175 name: sshd-SshClient[ad946082]-nio2-thread-2
—
org.apache.sshd.common.session.helpers.AbstractSession.doWritePacket(AbstractSession.java:873)
WAITFOR(encodedLock)
................
—
org.apache.sshd.common.session.helpers.AbstractSession.handleMessage(AbstractSession.java:362)
LOCKED(sessionLock)
Thread #22180 name: sshd-SshClient[ad946082]-nio2-thread-7
—
org.apache.sshd.client.session.ClientSessionImpl.signalAuthFailure(ClientSessionImpl.java:151)
WAITFOR(sessionLock)
.................
—
org.apache.sshd.common.session.helpers.AbstractSession.doWritePacket(AbstractSession.java:876)
LOCKED(encodedLock)
Attached you can find a full thread dump regarding the new deadlock. (see file
[email protected])
Let me know if you prefer open a new ticket and troubleshoot this issue.
Kind Regards
Roberto Deandrea
